          Your system is looking for this key of 16D8F9F5. It is the last 8 numbers of the whole string. According to the web site of the ppa that is looking for that key http://ag-projects.com/news/new-openxcap-release-107/ all you should have to do is to run the following line to install the key:



          sudo wget -O /etc/apt/trusted.gpg.d/agp-debian-key.gpg http://download.ag-projects.com/agp-debian-key.gpg


          Just as a test I ran it and I see that key now installed:



          sudo apt-key list
